Plexus PDF

Plexus PDF — Offline PDF Studio & Scanner Your documents never have to leave your phone. Plexus PDF is a complete, private PDF toolkit that works 100% offline. No accounts. No trackers. No uploads. Every merge, edit, scan and sign happens right on your device. PDF Studio tools Merge & organize Combine multiple PDFs into one document. Drag pages to reorder them, rotate individual pages, remove the ones you don't need and add page numbers. Sign & watermark Draw your signature once, tap anywhere on a page to place it, and burn it in permanently. Add text watermarks like "Confidential" or "Copy" in your choice of colour and size — apply to one page or every page. Split & extract Break a big PDF into single-page files, or pick exactly the pages you want and extract them into a new document. Convert Convert PDF pages to sharp JPG images, pull out all selectable text, turn photos into a PDF, or compress heavy scanned files to shrink their size. Edit Add real, selectable text anywhere on a page — in sans, serif or monospace. White-out mistakes, black out sensitive information, highlight important lines, draw boxes and underlines, or delete entire pages. You can even update the document title, author and keywords. Document scanner Use your camera to capture papers, receipts and whiteboards, or pick photos from your gallery. Crop each page exactly, apply a black & white or greyscale look, rotate anything that's sideways, and combine all your scans into a single PDF. History Every document you export is kept in a private on-device history, so you can reopen, share or delete any file at any time. Privacy first by design Plexus PDF has no servers. There is nothing to upload to — your files simply never leave your device. The INTERNET permission exists only for the built-in WebView; the app itself works fully offline at all times. Phone-friendly A fast, friendly interface designed for one-handed use on your phone, with light and dark themes and buttery-smooth motion. Free Plexus PDF is free to use.
